Tales of Eternia

To be able to access New Game+ without having to play the game twice, complete the game all the way past the six elementer pillars in Shisel's Castle. Then activate the lift. Enter the dungeon, but DO NOT go any furthur than the first screen. It should look like a purple stairway. Then, simply exit the dungeon the same way you came in and your file should be in New Game+ mode.

In Tinnsia, while participating in the "expensive sushi" contest with Kong the Man, play the contest through normally, eating (or not eating) any sushi you choose. -- When time runs out and BEFORE the "LOSE!" appears on the results screen, press triangle. -- The scene will return to Reid and Kong the Man in the building -- however, whether you actually won or lost the mini-game, Kong the Man will treat the results as though you won, congratulate you on a job well done, and award you the title! This glitch may be repeated as many times as the mini-game is played, although the title will only be rewarded once.

To unlock this dreaded dungeon, you must complete the game once, unlock the New Game +, and play the game. It is located on Orbus Barrier.

To access the New Game+ mode, successfully complete the game once and save. When you restart the game, you will have the option to choose New Game+. New Game+ allows access to a bonus dungeon and a new difficulty level.

Just enter a battle and get killed. Now on the slection screen where you can choose "Retry", "End", or "Load", pick "Load" and then cancel back to the selection screen. Every time you see the selection screen (including the first time you see it), count up from wherever your "death counter" is at the moment. Keep selecting "Load" and immediately cancelling back to the selection screen until you see the selection screen for the 100th time, and then pick "Retry". Now save your game and you'll notice that your "death counter" is at 100 and you have the "Survivor" title!
